ceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that chan es in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings l Figure 1 shows in elevation, a device constructed in accordance with the invention, the machine being arranged as it' will appear when the ring is being seated; f

The hydraulic press may be of various kinds, without de arting from the spirit of the invention. ince any particular' hydraulic press is a separate invention from the device 4herein disclosed, the press will be described briefiy. The hydraulic press may comprise a body 1 carrying a fixed cylinder 2 on which amovwable piston 3 is' mounted to reciprocate. The

press is operated by a handle 4, and the nu# 4meral 5 designates means for operating ,the

relief valve of the press. It is with such a press, or with a similar press, that the device 'man PRESS 1931. Serial No. 547,381.

forming the subject matter 4of this applica- I tion is adapted to be used.

A bracket 6 is fixed to the upper end of the piston 3. Thrust members 7, such as legs,

are pivoted at 8 to the .bracket 6, to swing '55 outwardly and inwardly. The legs or thrust members 7 may be of the angular form as shown in Figure 1 of the drawings, so that the lower ends of the leg-s will exert, as nearly as possible, a vertical thrust on the parts with which they coact, in the operation of the Inachine. i Y

At its ends, the body 1 ofthe press is provided with pairs of ears 9 having seats 10 in their upper edges. y' Rigid tension members 65 11, which may be pieces of pipe, are disposed between the ears 9. Thev tension members 11 havel a plurality ofv vertically spaced cross varms 12, providing for vertical adjustment of the tension members 11, the cross arms l12 0 being received in the seats 10 which are formed in the upper edges of the ears 9. At their lowei` ends, the tension membersll have slots 14 in which transverse anchors 15 are pivoted as shown atr16.

Figure 1 shows the machine placed to seat the ring 22 on the rim 17 of a vehicle wheel, opposite to the fixed flange 21 of the rim. The body portion of the wheel is marked by the numeral 28, and has a central opening 18, and other, smaller openings 19 disposed thereabout. -The tire-is marked by the numeral 20.

Y Let it be'supposed that, as shown in Figure 1, the `machine is arranged to force the ring 22 inwardly upon the tire 20. Then the ten- 85 sion members `11 are inserted downwardly through the openings 19 of the body 28 of the wheel, it being possible to turn the a-nchors 15 into alignment with the tension members 11 so that. the` tension members can'be inserted downwardly through' the o enings draulic press, by locating any desired ones of the cross arms 12 in the seats 10. The legs or thrust members 7 are swung outwardly, and their ends are engaged with the ring 22. It is obvious that by operating the press, through. the instrumentalityof'the handle 4, the tension members 11 will pull upwardly on the body 28 of the vehicle wheel, the ring 22 being crowded downwardly to a seat, through the instrumentality of the thrust members 7, which have grooves 29 in their lower ends so that they will not slip off the ring 22.

In order to take the tire 2O olf the rim 17, the tire and the rim are turned upside down,- after the ring 22 has been removed. This operation will be understood readily when Figure 2 of the drawings is noted, although that figure shows the machine in use upon a wheel body which differs slightly from the on'e shown in Figure 1 of the drawings.

In Figure 2, parts hereinbefore described have been designated by numerals previously used,'with the suilix a. The. modification in the wheel body arises out of the fact that the openings 19 of Figure 1 are not present. In, carrying out the operation contemplated in Figure 2, the lower ends of the legs 7 areI placed against the tire 20a. The tension meiners 11 are extended downwardly through the l central opening 18a of the wheel body 28a.

Recourse is had to a longitudinally extensible-cross piece 23 which isshown in detail in Figure 5 of the drawings. The cross rpiece 23 is composed of two parallel rigid members 24, which may be thickened slightlyl at their outer ends, as shown at 25. Each of the members 24. is provided at one end with a laterally disposed arm 26, in which the other ofi-said 24 are spaced apart by the arms 26, so that not be handled conveniently anyother way.

Having thus'described the invention, what.

2. The combin'ationwith a hydraulic press, includ-ing relatively movable piston and cylinder members,of legs pivoted to one of said relatively movable members for inward and out-ward swinging movement, tension members connected'to the other of said relatively movable members of the press, a longitudinally extensible cross piece, and' means for ,y

. an opening 27 exists between them. It is through this opening that' the tension members 1l pass, as shown in Fi ure 2 of the drawings, the cross piece 23 being supported on the anchors 15, and the member23 extending across the opening 18a, and engaging the lower surface of the wheel body 28a. It is desirable to have the cross piece 23 adjustable as to length, so that it. will span the opening 18a, regardless of whether the @opening 18a is large or small, and the cross piece can be shortened, so that its endswill not. engage the my own, I have hereto axed my signature.. members 1s received slidably.

With the parts arranged as shown in Figure 2 of the drawings, itis obvious that by operating the'.hydaaulic press,the tension i `members 11 will pull upwardly on the body 28, and the thrust members 7 will push down-l wardly on the tire 20a, thereby removingt-he tire from the rim 17a. p The device forming the subject matter of this application is simple cin construction, but it will be found to be highly useful and efficient for use on vehicle wheels which, owing to size, rusting, or any other' cause, can-
